如果你的 FastAPI 是单个文件，例如没有`./app`目录的`main.py`，则你的文件结构可能如下所示：

```
.
├── Dockerfile
├── main.py
└── requirements.txt
```

然后你只需更改相应的路径即可将文件复制到`Dockerfile`中：

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)
COPY ./main.py /code/

```Python
response = requests.get("http://example.com/some/url")
```

Відповідна операція *роуту* API FastAPI може виглядати так:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
     return {"message": "Hello World"}
```

Зверніть увагу на схожість у `requests.get(...)` і `@app.get(...)`.

```
.
├── Dockerfile
├── main.py
└── requirements.txt
```

Тогда в `Dockerfile` нужно изменить пути копирования:

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)!
COPY ./main.py /code/

```Python
response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.

Die entsprechende *Pfadoperation* der FastAPI-API könnte wie folgt aussehen:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

그러면 여러분들은 `Dockerfile` 내에 있는 파일을 복사하기 위해 그저 상응하는 경로를 바꾸기만 하면 됩니다:

```{ .dockerfile .annotate hl_lines="10  13" }
FROM python:3.9

WORKDIR /code

COPY ./requirements.txt /code/requirements.txt

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)
COPY ./main.py /code/

response.field.content_title=content_title
# Field name for content description in the response.
response.field.content_description=content_description
# Field name for URL link in the response.
response.field.url_link=url_link
# Field name for site path in the response.
response.field.site_path=site_path
# Maximum length of content title in the response.
response.max.title.length=50
# Maximum length of site path in the response.

```Python
response = requests.get("http://example.com/some/url")
```

La operación de path equivalente en FastAPI podría verse como:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

```Python
response = requests.get("http://example.com/some/url")

A contra-parte na aplicação FastAPI, a operação de rota, poderia ficar assim:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```
